. 8. H. pterocarpa, F. Muell. in Trans. Vict. Inst. 1855, 126, and in 
ook. Kew Journ. viii. 69. Very near H. plebeia, differing only in the winged 
fruits, glabrous, creeping, and rooting at the base. Leaves orbicular-cordate 
or reniform, doubly crenate or obscurely lobed, about 4 to 1 in. diameter, on 
small globular head of rather numerous flowers almost sessile. Bracts small. — 
Petals valvate. Fruits rather broader than long, notched above and below, 
very flat, with 2 prominent ribs on each side, attaining sometimes fully 2 lines 
diameter, the acute dorsal edge of the carpels being expanded into a wing.—

The species is also in New Zealand. The dilatation of the fruit appears to be somewhi 
variable, and it is possible that it may prove to be a variety of H. plebeia.

Hook. Kew Journ. viii. 70 ; Fragm. iv. 181. Glabrous or rarely s rinkled 
with a few hairs; stems lax, diffuse, often rooting at the lower joints, lto ` 
2 ft. long or more. Leaves deeply divided into 3 to 7 lanceolate-acute - 
toothed or lobed segments, the larger central one often above 1 in. long; the : 
lower leaves sometimes slightly peltate. Stipules fringed. P uncles

When large and luxuriant, the species bears some outward resemblance to the Mai ` d 
quinqueloba, Ruiz and Pav., but the fruit is quite different. In the latter respect as WE — 
in the habit it comes near to Trachymene procumbens, but is at once known by 
bracts.
